Ezekiel Sims and the Intellectual Property of Marvel Characters

Published on May 29, 2026 | Translated from Spanish

The creation of Ezekiel Sims by J. Michael Straczynski and John Romita Jr. for Marvel Comics presents a classic case of work for hire in the comic book industry. This character, a businessman with totemic spider powers, not only enriched Spider-Man's lore but also exemplifies how copyright ownership falls to the publisher, not the original creators, under the US legal framework of work made for hire.

Legal framework of work for hire in comics ⚖️

Under US copyright law, when an artist or writer creates a character like Ezekiel Sims within an employment or commissioned contract for Marvel, the intellectual property belongs to the corporation. This means Marvel holds exclusive control over the exploitation of the character in any digital medium, from video games to NFTs. The legal doctrine of copyright on fictional characters requires them to be sufficiently developed (physical traits, personality, name) to be protectable. Sims, with his distinctive design by Romita Jr. and his dark mentor narrative by Straczynski, meets that threshold, but the economic benefit from his use on digital platforms belongs entirely to Marvel, barring specific royalty agreements.

Digital implications and the future of rights 🔮

The digital exploitation of characters like Ezekiel Sims raises questions about compensation for original creators. While Marvel can license his image for a video game or mint an NFT without needing permission from Straczynski or Romita Jr., these authors often rely on historical contractual clauses. The legal reflection here is whether the rise of the metaverse and digital assets justifies a review of intellectual property laws to balance corporate power with the moral and economic recognition of the artists who brought these icons to life.

Considering that Ezekiel Sims was created under a work for hire agreement, what moral and economic rights do Straczynski and Romita Jr. actually retain over their character, and how does this affect legal authorship in other media such as film or video games?
